Are you filtering attachments?

Yes, to minimize the spread of email-borne virus attacks and in accord with "best practices," email attachments into or out of the email servers are scanned. Email attachments are scanned by Google servers.

Anti-virus scanning attachments

Gmail automatically scans every attachment when it's delivered to you, each time you open a message, and attachments you send to check for viruses. This helps to protect everyone who uses Gmail, and prevents the spread of viruses.

What happens if a virus is found?

If our system is unable to scan certain files, you'll see an error reading 'Oops... the virus scanner has a problem right now.' You'll have the option to try again later or to download the attachment at your own risk. Please note that if Gmail can't scan the contents of the file, we can't guarantee that it's safe to view.  About anti-virus scanning
